The present invention relates to an advanced water treatment apparatus using a manganese manganese tower, and more particularly, a raw water tank unit for storing raw water and activating the performance of the manganese manganese tower, iron, manganese, dissolved organic matter, suspended matter and manganese in raw water. Manganese tower to remove the components, backwash tank unit for backwashing of manganese tower, circulating water tank unit to remove odors and odors in the filtered manganese tower filtration and to serve as raw water storage of membrane filter, residual turbidity in the circulating water, virus and It comprises a membrane filtration unit for removing pathogenic microorganisms, a production tank unit for storing and supplying the production water passed through the membrane filtration unit, and an automatic control unit for controlling and monitoring the respective units.

Currently, the standard water purification process in Korea is somewhat different depending on the water purification plant, but generally, the raw water tank which takes in raw water, the cohesive mixing tank which mixes with coagulant, the sedimentation tank which precipitates cohesive mixed raw water, and the supernatant of the settling tank are filtered. This is followed by a sand filtration tank and a disinfection process. However, these current processes have problems such as the discovery of new harmful substances, the difficulty of simultaneous removal of pathogenic bacteria and disinfection by-products, as well as the difficulty of coping with deterioration of water quality of drinking water. In addition, poor conditions such as small and medium-sized water purification plants and simple water supply due to the aging of existing facilities and lack of professional manpower may lead to water pollution accidents.

As an alternative to this, drinking water facilities using membranes are emerging during various processes, but this is also inefficient due to lack of domestic technology and experience and inadvertent introduction of foreign technologies. Moreover, the design of the entire process including pretreatment by raw water quality analysis and the lack of experience in designing the treatment flow rate of the membrane, which are the most important of the membrane process design, are designing the flow rate less than 1m / d, which causes the initial installation cost. In addition, even in the film material, a situation in which materials such as PS, PP, PE, CA, and PAN are poor in chemical resistance and physical resistance are introduced. In particular, due to the lack of awareness of the importance of the most important pretreatment equipment for membranes, the shortening of membrane life due to secondary pollution that may occur after membrane filtration and the contamination of production water are being overlooked.

The present invention has been made to solve the above problems, in the present invention by applying a manganese tower to remove the iron, manganese, dissolved organic matter and turbidity-causing substances in the raw water to maintain the performance of the membrane and to extend the life and existing flocculation And significantly reduce the site required for the sedimentation tank to provide a process technology capable of reducing the manufacturing cost of water, and also by applying polyvinyldiene fluoride (PVDF) in addition to the PS, PP, PE, CA, and PAN as the material of the membrane, chemical resistance and physical resistance The technical challenge is to improve the permeation flux of the membrane to 2-4m / d, reduce the initial investment cost, and provide drinking water of good quality.

In the raw water tank unit 10, a pH adjuster, a flocculant (PAC) and sodium hypochlorite (NaOCl) are added in order to activate the performance of the manganese tower 20. It may vary.

The present invention transfers the raw water of the raw water tank unit 10 to the manganese tower 20 through the manganese tower supply pump 21 and the manganese tower contains iron, suspended matter, dissolved organic substances, etc. contained in the raw water. It aims to have the function of removing, and at the same time, it has a special function to remove the manganese component which is attached to the surface of the membrane during filtration and oxidizes the membrane to reduce the performance and life of the membrane and cause black tube phenomenon.

The manganese tower 20 is composed of gravel, manganese sand and anthracite. More specifically, the size of manganese sand is 2 mm, the size of anthracite is 5 mm, and the height of the layer is manganese sand 600 mm, anthracite 200 mm. Is preferably 10 m / s. However, the size and quantity of the manganese tower 20 and the size and amount of the media constituting the manganese tower 20 may be appropriately determined according to the quantity to be treated.

The present invention has a backwash tank unit 30 for storing the filtered water passed through the manganese tower 20, supplying it to the circulation water tank unit 40, and cleaning the manganese tower 20. As raw water is filtered in the manganese tower 20, foreign substances such as solid materials, organic materials, and manganese components are accumulated in the manganese tower 20, thereby degrading the performance of the manganese tower 20 and reducing filtration efficiency. Let's go. Therefore, it is necessary to remove the foreign matter in the manganese tower 20 and to this end, it is necessary to supply the backwash water from the backwash tank 30 to remove the foreign matter. For this purpose, the backwash water of the backwash tank 30 is backwashed. It is supplied to the manganese tower 20 through the pump 31 to remove the accumulated foreign matter in the manganese tower through the backwashing process is drained.
